Technical field
The present invention relates to a kind of whole row's screen cabinet for relay protection chamber to realize the device of separate ventilation in it.
Background technology
Existing integral cabinet of relay protection chamber, it is usually connected by several screen cabinet monomers and forms, and left and right outermost is furnished with limit screen, all the other inner connections.As whole row's screen cabinet of 110kV and following transformer station, want the screen cabinet monomer of about 8, and the whole row of 220kV and above transformer station is shielded cabinet and may be formed by more shielding cabinet monomer.Itself is not mostly with Design of ventilation, and not only its internal unit self-heating can not shed, and also may, because of temperature control, cause critical component useful life and effective controlling to decline.Even if some powerful device adopts the upper exhaust system design of single screen cabinet monomer once in a while, also just fan base is directly installed on inside certain top board shielding cabinet monomer, only can realize the ventilation of single screen cabinet monomer, and its maintenance is extremely inconvenient, not only uneconomical but also easily cause interior arrangement dust stratification, transform difficulty after putting into operation large.
Summary of the invention
The object of this invention is to provide the device that a kind of installation and maintenance are convenient, can realize good ventilation inside and outside whole row's relay protection chamber screen cabinet.
For achieving the above object, the technical solution used in the present invention is:
A kind of ventilation device for integral cabinet of relay protection chamber, be arranged in integral cabinet of relay protection chamber to realize the circulating ventilation between its inside and outside, described integral cabinet of relay protection chamber comprises by the multiple screen cabinet monomer successively connected screen cabinet body formed, the sidepiece of the screen cabinet monomer described in outermost two has oral area and is coated with dismountable limit screen, the junction of the side of the screen cabinet monomer described in all the other is all communicated with, described ventilation device for integral cabinet of relay protection chamber is arranged on the described limit screen of the outside portion of the screen cabinet monomer described in outermost two, it comprises the lower air inlet of the bottom of the limit screen be arranged at described in side and is arranged at the upper exhaust outlet on the top that the limit described in opposite side is shielded, described lower air inlet is communicated with the inside and outside both sides of described integral cabinet of relay protection chamber respectively with described upper exhaust outlet.
Preferably, described lower air inlet is provided with the air intake filter protection net it covered completely.
Preferably, described lower air inlet is provided with air inlet fan.
Preferably, described air inlet fan is installed in air inlet fan box, and described air inlet fan box is installed on the side of the inside of the close described screen cabinet body of described limit screen.
Preferably, described upper exhaust outlet place is provided with the air draft filter protection net it covered completely.
Preferably, described upper exhaust outlet place is provided with air ejector fan.
Preferably, described air ejector fan is installed in air ejector fan box, and described air ejector fan box is installed on the side of the inside of the close described screen cabinet body of described limit screen.
Ventilation unit of the present invention can utilize the lower air intake of a side screen and the upper air draft of another side screen, also can open air inlet fan and air ejector fan where necessary, make the thermal current that in screen cabinet, self thermal source produces form natural circulation, the hot-air in screen cabinet is discharged, realizes ventilation function.
Because technique scheme is used, the present invention compared with prior art has following advantages: 1, ventilation unit of the present invention is arranged on the dismountable limit screen of integral cabinet of relay protection chamber, install and easy maintenance easy; 2, ventilation unit of the present invention can solve the ventilation and heat requirement of whole row's screen cabinet inside well, effectively can improve the running environment of the device systems in integral cabinet of relay protection chamber.
Accompanying drawing explanation
